The Interstate 5 Freeway ( I - 5 ) through the cities of Irvine and Tustin is essential to Orange County ’ s mobility , economy and quality of life . It is a major commuter and commercial corridor , and serves as a “ bridge ” that connects Orange County to Los Angeles County and San Diego County .

Most SR - 55 drivers live in the area or travel there to visit local businesses on or near Newport Boulevard . At the terminus of the Costa Mesa Freeway , at 19th Street , close to 100 , 000 vehicles pass through this area on a daily basis , and these volumes are projected to grow in the future .

A new drainage system is being constructed along northbound SR - 55 adjacent to the Kenyon Pointe and El Paseo properties . Crews are currently constructing the new drainage system and will remove the existing drainage system once the new one is in place .

This Program represents the culmination of years of collaboration and support of environmental communities . In November 2010 , the Board allocated $ 42 million to purchase open space in Orange County . To date , OCTA has acquired more than 1 , 300 acres in Brea , Laguna Beach , Silverado Canyon , and Trabuco Canyon .

Through its continued outreach efforts , OCTA is fostering relationships with numerous civic , social and business communities to serve an increasingly diverse population in Orange County that continues to grow and evolve .

Therefore , the Long - Range Transportation Plan ( LRTP ) is developed every four years to define a vision for Orange County that aims to address future mobility needs . This vision considers a forecast of available revenues , changing demographics , and any other significant trends .
